DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

 The browser use tool lets Claude navigate, read, and interact with webpages in a browser that your application runs. It works with the page both through its structure (the accessibility tree, elements, forms, and tabs) and through pixels (screenshots and viewport coordinates), whereas the [computer use tool](https://platform.claude.com/docs/en/agents-and-tools/tool-use/computer-use-tool) works with a whole desktop through screenshots and coordinates alone. It's an Anthropic-defined [client toolset](https://platform.claude.com/docs/en/agents-and-tools/tool-use/tool-reference#client-toolsets): one `browser_toolset_20260801` entry in your `tools` array gives Claude 27 member tools by default, such as `navigate`, `read_page`, `left_click`, and `screenshot`, plus four more (`javascript_exec`, `file_upload`, `read_console`, and `read_network`) when you [enable them](https://platform.claude.com/docs/en/agents-and-tools/tool-use/browser-use-tool#enable-optional-member-tools). Your application runs every call against its own browser automation; nothing runs on Anthropic's side. It isn't currently available in [Claude Managed Agents](https://platform.claude.com/docs/en/managed-agents/tools). This page says "your application" for the agent loop that calls the Messages API and "your executor" for the part of it that drives the browser and produces tool results.

 ## Quick start
 
-The browser use tool is available on the Claude API with no beta header: add one entry of type `browser_toolset_20260801`, with no `name`, to the `tools` array of a [Messages API](https://platform.claude.com/docs/en/api/messages/create) request.
+The browser use tool is available on the Claude API and [Google Cloud](https://platform.claude.com/docs/en/build-with-claude/claude-on-vertex-ai): add one entry of type `browser_toolset_20260801`, with no `name`, to the `tools` array of a [Messages API](https://platform.claude.com/docs/en/api/messages/create) request.

 ## Limitations
 
-* **Platform availability:** Browser use is available on the Claude API only.
+* **Platform availability:** Browser use is available on the Claude API and [Google Cloud](https://platform.claude.com/docs/en/build-with-claude/claude-on-vertex-ai).
 * **Whole-input streaming only:** When you stream, each member's `input` arrives as one complete `input_json_delta` ([Client toolsets](https://platform.claude.com/docs/en/agents-and-tools/tool-use/tool-reference#client-toolsets)).
 * **Element references are best-effort:** Highly dynamic pages (virtualized lists, canvas-rendered interfaces, pages that re-render on scroll) might not expose stable references, and Claude falls back to screenshots and coordinate clicks there.
 * **`read_console` and `read_network` depend on your browser automation:** They report only what it can capture, and only from the moment it attached to a tab.
